To all whom it may concern:

' Be it known that I, HERBERT S. PUTNEY, a citizen of the United States,residing at Sandusky, in the county of Sanilac and State of Michigan,have invented a new and useful Im rovement in PipeC oupl1ngs, of

which the following is a specification.

This invention relates to ipe couplings and more particularly to coupings for corrugated pipes, used for culverts and water mains, the objectbeing-to provide a coupling which is'very simple and cheap in con--struction and one which will overcome the difficulties now existing inriveting the sections together.

Another object of my invention is to provide a pair of coupling membersadapted to be clamped together over the meeting end of the sections.

This invention consists of the novel features of constructionhereinafter fully described, and pointed out in the claims.

In the drawings forming a part of this -specification:-Figure 1 is aperspectiveview of the pipe section partly broken away, showing thecoupling member in place. Fig. 2 is a detail longitudinal sectional viewof the pipe section showing the coupling members in place. Fig. 3 is adetail longitudinal sectional view showing an extra ring arrangedbetween the coupling members. Fig. 4 is a detail plan view of thesection. Fig. 5 is a section taken on the line 5-5 of Fig. 2. Fig. 6 isa section taken on the line 66 of Fig. 3.

In the drawings forming a part of this specification A, and B, indicatea pair of coupling members adapted to connect the ends of the corrugatedpipe section.

The member A is preferably formed of an oblong block having beveled endsand, a

transverse fluted face adapted to be arranged under the meeting ends ofthe corrugated sections 0, which are provided with notches C,registering with each other. An opening is formed through the center ofthe member A, surrounded by'a square recess on its bottom in which thehead of a bolt D, is adapted to be secured, which passes up throughopenings in the block and out through the notches in the pipe sectionsC.

The member'B, isformed of an oblong block havingbeveled ends and atransverse v concaved face rovided with a central openin The b100 1 isadapted to fit over the boIt D, and be clamped over the meeting ends ofthe sections 0, by the nut D.

When it is desired to form a perfect Water joint, a ring E is placedover the meeting ends of the sections under the block B, provided withan opening throughwhich the bolt 1), is adapted to pass.

It is of course understood that any number of these menihere can be usedas desired.

From the foregoing description it can be readily seen that .I haveprovided a pi e coupling which can be easily and quicky attached and onethat is very effective in use.

Havin thus fully described my invention, what I claim as new and desireto secure by Letters Patent is 1. Apipe coupling comprising flutedblocks adapted to be arranged under and over the ends of the pipesections a ring arranged over said sections, and means for clamping saidblocks together for thepurpose described.

2. A pipe coupling comprising a fluted' block adapted to be arrangedunder the end of the pipe sections, a ring arranged over said ends, aconcaved block arranged over said ring, and means for clamping saidblocks together; for the purpose set forth.

3. In a pipe coupling, the combination with notched pipe sections, of afluted block arranged under the meeting ends of said sections, a rinarranged over said ends, and a concaved b ock arran ed over said ringconnected to the fluted lock, for the purpose described.

4. A coupling for corrugated pipe comprising a transverse flutedapertured block adapted to be arranged under the notched endsof thecorrugated pipe sections in the grooves and ribs of the same, atransverse concaved apertured block adapted to be ar ranged on saidnotched ends of the pipe sections over the ribs of the same, and a boltadapted to pass through said block and notched ends and lock the blockstogether for the purpose described.
